Use FAIL instead of internal macro

[pinventado]

https://github.com/ILXL/cpp-code-analyzer/blob/c627448b9d329bae4aa2972dc477bc2767f171cc/src/test/gtest_ext.h#L156

Can we replace this with FAIL() instead?

FAIL() << " timed out (> " #secs
" seconds). Check code for infinite loops"; \

This will use an exposed macro rather than something that is used internally by google test
